Second blade, 10 length substantially 170mm is about 10mm than the first blade 9.Such benefit is to improve particle and crushing
Residence time in chamber 1.
Specifically, fluid can be rapidly dispersed into 8 edge of disk body by the first blade 9, and the second blade 10 can be by fluid
It is recycled back to 8 edge of disk body, since discharge space 12 is located at the lower surface of disk body 8, under normal circumstances, discharging is all by that can produce
The blower of raw negative pressure provides fluid mobilization dynamic.In the case where not blowing in machine, rotating grating disk 2, we can be found that gas is
It flowing to from down and goes above, the direction under this is flowed to fluid in normal production from above is different, and we may safely draw the conclusion in this way,
Longer second blade 10 can produce relatively large air pressure.This phenomenon be applied in actual production will generate it is more peculiar
Effect, i.e., blower generate negative pressure, the fluid of 2 lower surface of grating disk has the tendency that flowing downward, while the second blade 10 compares
